So yesterday, I had a kid ride along with me who was running the exact same car with the same setup as I had. He told me the things he noticed about my driving that other people noted, then I rode with him. His time was about six seconds quicker than mine, so it was like “hmm. So that’s what my car can do, so I just need to close that gap with my driving.”
Next session, kids dad rides along with me. I’ve had instructors with me before who quietly direct me as I go, and this was not one of them. He was YELLING in my ear, “MORE THROTTLE MORE THROTTLE!! NOW BRAKE HARD! KEEP IN IT,” etc. Like at the top of his lungs and relentlessly screaming.
I picked up four seconds.

Tldr; have someone scream if u wanna go fast
